Plan drawing of a triplex on a 16.3 by 19.4 metre lot, 2 storeys, 3 dwellings, 20 rooms. Dwelling U0 (2BR) has 6 rooms totalling 60 square metres. Dwelling U1 (2BR) has 6 rooms totalling 52 square metres. Dwelling U2 (2BR) has 6 rooms totalling 111 square metres. Building footprint 127 square metres; open space 192 square metres. This design is infeasible; failing categories: insufficient area. Objective scores, higher is better: density 0.95, daylight 0.35, privacy 0.83, circulation 0.62, carbon 0.77, cost 0.46.
